Engineering services since 1915 

Dr.-Ing. Otto Mohr initially established the German Environmental Consultants (DAR, for short in German) in 1915 in Wiesbaden.

DAR is one of the first companies in Germany to deal with the technical problems of environmental protection and offer solutions.

In the founding period, the DAR developed many recognized process methods in wastewater technology and obtained numerous patents. These innovations were only made possible by research projects in cooperation with German and European universities. In combination with its state-approved laboratory services for wastewater, sewage sludge, and soil analysis, DAR has succeeded in decisively shaping the technological trends in the field of environmental technology over the years.

DAR has planned and supervised the construction of environmental protection facilities for countless cities, municipalities, associations, and industrial companies.

A staff team of over 35 co-workers, at least 20 of whom are engineers (or with equivalent professional qualifications), provides excellent project management for our clients at the head office in Wiesbaden.

The specialization in environmental technology and many years of experience and developments ensure that every task is handled individually and solved expediently.

You, too, can benefit from our know-how for your projects!
